|This article is about a/an race of monsters in Tensou Sentai Goseiger.|
The poisonous Bibi Bugs (ビービ虫 Bībi Mushi?), created by Buredoran of the Comet, are living products from the dark aspects of previous alien races Warstar conquered. After Warstar fell, Brajira kept the Bibi Bugs' hive to utilize them for the Yuumajuu before Kinggon takes it. When Kinggon was destroyed, the Bibi Bug Hive ended up in Metal Alice's possession, modifying them to convert into Bibi Nails to enlarge Matroids.
Eventually the Bibi Bugs are destroyed after Brajira's death. However, one Bibi Bug survives and evolves into a humanoid form called King Bibi (キングビービ Kingu Bībi?) who enters the body of Yumeko Hoshino in order to execute a master plan that would destroy the Goseigers and everything they stood for in order to avenge his kind while feeding on the darkness in human hearts. However, King Bibi's plan fails and he is destroyed soon after by Ground Gosei Great.
- The Bibi Bugs are a reference to B-movies, in keeping with Goseiger's theme of its monsters being named for various Hollywood films.
- The circle that appears in front of a defeated monster about to be turned giant is similar to the circle that appears when Kamen Rider Rey and Kamen Rider Arc transform.
